Ethanol gasoline vs pure gasoline vs pure gasoline, which is better for a car engine?

<> of course is ethanol gasoline.

Well, 1. Ethanol gasoline burns quickly, which can allow car owners to refuel more, consume more, and increase taxes! 2. Ethanol gasoline accelerates the aging of vehicle parts, allowing car owners to maintain and repair their cars more, promote consumption, and increase taxes! 3. Ethanol gasoline is environmentally friendly, ethanol is made of grain, food is a renewable resource, I don't want oil to burn a little less!

The times are advancing, there is nothing wrong with the upgrading of automobile oil, and the power of pure gasoline is strong, which is well known, but the exhaust gas is serious, and the raw material of pure gasoline is not renewable energy.

It was necessary to find alternative renewable energy products, so ethanol fuel was born, which is also a new power source for sustainable development.

Although the power of ethanol gasoline is weaker, there is a certain erosion of the engine and oil circuit, and the defects of ethanol gasoline can be solved by adding some special additives in the future.

To say that ethanol gasoline is environmentally friendly is definitely a false proposition.

Ethanol combustion value.

It is only 60% of gasoline, and the production of ethanol mainly depends on corn, and the need for chemical fertilizers and pesticides in the production of corn is only a matter of pollution transfer. Ethanol production has boosted corn**, so many soybeans have been planted with corn, which has increased the soybean gap. So the promotion of ethanol gasoline is just a decision to sit in the office.

Definitely does more harm than good.

Ethanol is alcohol, and it is known in chemistry classes that ethanol produces water after combustion, and the consequences of using ethanol gasoline are very serious, causing a lot of damage to the car, and the exhaust pipe does not smoke but drains water. The engine not only has serious carbon deposits, but also embroiders and burns oil.

The car will be a large piece (after a period of use. The car is weak and weak, and the spark plugs.

Absolutely early replacement.

It's normal to be bored. Calorific value of ethanol.

It is 60% of gasoline, and 6% less power. Ethanol ** is enough, and many cars are not suitable for ethanol gasoline. Wait for more ** pure gasoline.

Ethanol gasoline must be relatively low in deflagration, so adding ethanol gasoline will feel that the power of the vehicle engine has been lost, which is a normal phenomenon and can be used appropriately with fuel additives.

It is certain that pure gasoline is good for the engine of the car, and gasoline with ethanol will accelerate the aging of the engine parts of the car. Now adding ethanol to gasoline is purely to protect the environment, and it does not do any good for the engine!

Pure gasoline is better for car engines because ethanol is volatile and unstable.

I think pure gasoline is better for the engine of the car, because pure gasoline contains less impurities, less damage to the engine, and with pure gasoline, the power of the engine will also be stronger.

Judging from the driving performance of the car alone, it is obvious that pure gasoline will be betterAfter all, the latent heat of vaporization of ethanol is large, and the evaporation temperature under the theoretical air-fuel ratio is greater than that of conventional gasoline. It affects the formation and combustion rate of the mixture, resulting in the decline of the power, economy, and cold start of the car, which is not conducive to the acceleration of the car.

These are also the reasons why many car owners are not very interested in ethanol gasoline. However, the promotion of ethanol gasoline has become imperative, and what we can do as car owners is to learn more about ethanol gasoline voltaic knowledge in order to respond to all changes.

Ethanol gasoline for automobiles has the following advantages as a clean engine fuel oil:

1. High octane number and good anti-knock performance.

2. The oxygen content of ethanol is as high as that. Gasoline contains 10% ethanol, and the oxygen content can be reached.

3. The use of ethanol gasoline for vehicles can effectively reduce automobile exhaust emissions and improve the energy structure. Domestic studies have shown that E15 ethanol gasoline (with an ethanol content of 15% in gasoline) has lower carbon and carbon monoxide emissions than pure unleaded gasoline for vehicles, and carbon monoxide emissions have decreased by 30%.

4. The production of fuel ethanol is rich in resources and mature technology. When less than 10% is blended into gasoline, ethanol gasoline can be used directly without major changes to the engine of the car in use.

Each has its advantages.

Advantages of ethanol gasoline over regular gasoline:

Ethanol is a renewable energy source and is produced by fermentation of sorghum, corn and potatoes. It does not affect the driving performance of the car and also reduces the emission of harmful gases. As a new type of clean fuel, ethanol gasoline is the focus of renewable energy development in the world, which is in line with China's energy substitution strategy and renewable energy development direction, is technically mature, safe and reliable, fully applicable in China, and has good economic and social benefits.

Ethanol gasoline is a mixture rather than a novel compound. Adding an appropriate amount of ethanol to gasoline as automobile fuel can save petroleum resources, reduce air pollution from automobile exhaust, and promote agricultural production.

Disadvantages: low calorific value.

The same volume of ethanol, its energy is only 2 3 times that of gasoline, and when it is mixed with gasoline, it actually reduces the heat content of the fuel. Therefore, with the same full tank of fuel, gasoline mixed with ethanol will only drive less mileage.

High evaporation potential.

The latent heat of evaporation of ethanol is more than 2 times that of gasoline, and the latent heat of evaporation will make ethanol fuel low-temperature start and low-temperature operation performance deteriorate, if the engine is not equipped with air intake preheating system, it is difficult for the car to start when burning all-alcohol fuel, but a low proportion of alcohol is mixed in gasoline, and liquid ethanol is supplied by the combustion chamber wall to evaporate heat, and the characteristics of large latent heat of evaporation can become a favorable factor for improving engine thermal efficiency and cooling the engine.

It is easy to produce air resistance.

The boiling point of ethanol is only, at the normal operating temperature of the engine, it is easy to produce gas resistance, reduce the fuel supply or even interrupt the oil supply, and corrode the metal.

Ethanol in the combustion process, will produce acetic acid, especially the car metal copper has a corrosive effect, some tests have shown that when the ethanol content in gasoline is less than 10%, there is basically no corrosion to the metal, but when the ethanol exceeds 15%, it must be added with a relatively corrosion inhibitor.

Poor adaptability to the material.

Ethanol is an excellent solvent, which is easy to cause slight corrosion, expansion, softening or cracking of automobile sealing rubber and other synthetic non-metallic materials.

Easy stratification ethanol is easy to absorb water, and the water content of automotive ethanol gasoline exceeds the standard index, which is easy to occur liquid phase separation, which affects the use.

Ethanol gasoline is not resistant to burn cars and has long been denied by foreign countries (Germany). Ethanol gasoline is ethanol extracted from grain and plant fiber, mixed with ordinary gasoline in proportion, with high environmental protection, belongs to renewable energy, the essence of ethanol is plants, so it is easy to produce carbon deposits after combustion, especially for old cars that are more than 3 years old, you can clean carbon deposits with just a tank of oil! After all, carbon deposition is a trivial matter, and we will clear the quilt if it is blocked!

But the problem is far from that simple! There is a major defect in ethanol gasoline, that is, the shelf life, ethanol gasoline only has a shelf life of 1 month, beyond the shelf life there is a possibility of stratification, and there is also a situation where stratification will occur, that is, in case of water, for example, if you add ethanol gasoline on a rainy day, there may be water! The layered ethanol gasoline is alcohol, water, and gasoline, and what happens when the engine enters the water, so I don't need to say more!

Next, I will tell you one more thing that I don't tell most people, another unknown secret of ethanol gasoline, ethanol is a soluble solvent, similar to alcohol! Even if it is mixed with ordinary gasoline, ethanol will account for more than 80%. So here comes the question, if you ask the experts, is ethanol gasoline corrosive?

That's what the experts will tell you! Ethanol is an organic solvent with excellent performance and strong dissolution and cleaning characteristics.

The engine can be cleared, and there are many benefits! If you ask me, I will tell you: ethanol gasoline is not only soluble in itself, ethanol also produces acetic acid during combustion, and acetic acid is very corrosive to automotive metals, especially copper.

After many times of adding ethanol gasoline and pure gasoline comparison, the biggest feature of ethanol gasoline is that it is not burning, and the car is boring! 45 liters of fuel tank, full of 92 ethanol gasoline run high speed 580 kilometers after just into Shanhaiguan oil lamp on, pure 92 gasoline full tank, and in Shanhaiguan car for two days, after returning, it must be longer than the original route, a tank of oil to run home, 657 kilometers! The oil lamp was not on, and it cost 28 yuan less to fill up No. 92 ethanol gasoline than to fill up pure No. 92 gasoline when I came back.

Ethanol 92 gasoline yuan. Pure No. 92 gasoline yuan! A rough estimate is that a tank of pure gasoline runs about a hundred kilometers more than a tank of ethanol gasoline!

And the engine sound is really different! Here's a recent comparison!

Of course, gasoline is less damaging to the engine, ethanol gasoline is just cheaper and more environmentally friendly, and the damage to the oil pump and cylinder is greater!

Ethanol fuel, also known as ethanol gasoline, refers to a new generation of clean and environmentally friendly vehicle fuel blended by a specific process in a special gasoline component oil (blended oil produced by a refinery or petrochemical plant for blending automotive ethanol gasoline produced by a refinery or petrochemical plant) that does not contain MTBE oxygenated additives, and is blended by a specific process in accordance with the quality requirements of the national standard GB18351-2004. The adjustment of energy structure and the reduction of environmental pollution have promoted the development of ethanol fuel.

The differences are as follows:

1. Different characteristics: ethanol gasoline uses fuel ethanol as a gasoline additive, which is environmentally friendly, clean and renewable. Ordinary vehicle gasoline is the use of chemical agents such as MTBE as raw materials as gasoline additives, which has great pollution to the environment, and many countries have banned additives such as MTBE.

2. The evaporation potential is different: the evaporation potential of ethanol is greater, which can be said to be twice that of gasoline, which can improve the thermal efficiency of the engine and the favorable factors for cooling the engine.

3. Different advantages: lower calorific value, compared with ordinary gasoline, the calorific value of ethanol gasoline is only 61%, and more fuel is required to drive the same distance than ordinary fuel, although the calorific value is much smaller than gasoline, theoretically the calorific value of the mixture is very close to that of gasoline, so ethanol can be used as gasoline engine fuel.

4. Different disadvantages: easy to produce gas resistance, if ethanol gasoline is used, it is easy to produce gas resistance under the normal working temperature of the vehicle engine, because the boiling point of ethanol is lower than that of ordinary gasoline, only about 78 degrees Celsius, which makes the fuel supply easy to reduce, and even cut off the oil halfway.

Gasoline use note:

The first criterion for choosing gasoline for a vehicle is the compression ratio, which is the ratio of the total engine volume to the combustion chamber volume. For example, a car with a compression ratio is suitable for 93 gasoline. The use of gasoline engines lower than the applicable mark is prone to deflagration, that is, the fuel is burned in advance in the engine, which will cause the engine power to decrease, fuel consumption to increase, and the car to accelerate and climb powerlessly.

After a long time, the engine will overheat, and the pistons, bearings, etc. will be deformed and damaged. Saving money by lowering the petrol mark will not only not save money, but will cause irreparable damage to the car owner. On the other hand, don't worship or superstitious high-grade gasoline, not to mention the high price of gas, it will not save you fuel when driving.

Tire width: The wider the width of the tire, that is, the larger the tire contact area, the more fuel is consumed. When the friction is high, the resistance to overcome will increase, and your car will pay a little more fuel for this increased resistance every moment of the journey.

As follows:

1. The ethanol in ethanol gasoline is a renewable resource, which can be made by fermentation of sorghum, corn, potatoes, etc., which is more environmentally friendly, but ordinary gasoline is non-renewable, and the emission of gas pollution is more serious.

2. The calorific value of ethanol is only 60% of that of conventional motor gasoline, so it will be a little worse than pure gasoline in terms of power and fuel economy.

IntroductionAccording to China's national standard, ethanol gasoline is made by blending 90% ordinary gasoline with 10% fuel ethanol. It can effectively improve the performance and quality of oil products, and reduce the emission of major pollutants such as carbon monoxide and hydrocarbons. It does not affect the driving performance of the car and also reduces the emission of harmful gases.

1. Ethanol gasoline is blended by gasoline and ethanol, and ordinary gasoline has no ethanol component;

2. Ethanol gasoline is more environmentally friendly and can significantly reduce vehicle exhaust emissions;

3. The calorific value of ethanol gasoline is lower than that of ordinary gasoline, and it is worse than ordinary gasoline in terms of power and fuel economy;

4. The ethanol component in ethanol gasoline belongs to renewable energy, and ordinary gasoline is not renewable energy;

5. The water solubility of ethanol gasoline is very good, while the water solubility of gasoline is a little worse.

Question: How to mix ethanol gasoline?

Answer: tert-butanol 1% 5%, isopropyl acetate 1% 5%, methanol 5% 20%, ethanol gasoline 75% 90%. When preparing reformed ethanol gasoline, tert-butanol, isopropyl acetate, methanol and ethanol gasoline are taken in turn according to the ratio, and added to the static mixer in the above order for mixing.
